What can I do about my father (88) who talks about sex most of the time and is disrespectful to females, including his caregivers?

My 19 year old niece is studying to be a nurse. She told me that her instructors have informed them that taking care of patients involves a lot of sexual harrassments. The instructor then gave some examples of what she has to deal with - groping, sexual comments, etc.... So, if these caregivers have had some formal training or from years of caregiving experiences, they will know that when it comes to elderlies - they lost their "filter". They will know that this is part of caregiving. BUT, when the comments now progresses to actual touching, again, it will depend on the caregiver's experience. If they are experienced enough, they can firmly remind the patient that it is inappropriate, etc....

Here are 2 links from this site that might help you. I did a Search engine on the top right of this site, using "elderly and sexual comments."

Most professional caregivers are well trained in how to handle these episodes, so I wouldn't worry too much about their reaction. You may feel better if you talk with someone at the AFL who works with your father. Choose someone you particularly like, so you feel safe. Then ask if he's ever talked with him or her about sexual activity. Likely he has. Bringing this topic out into the open should help you cope.
We hate to see our loved ones act in such an undignified manner, but it happens. Nurses and CNAs are generally aware that they can get grabbed or swatted on the behind. They can be asked directly for sex. They can be pelted with sexual language that would shock family members. But most professionals take this in stride.

I would tell your father what he don't want to hear.Sad but,sometimes a little fib goes along way.Warning him should scare him enough to stop calling names and watching his month.Tell him a fib like,Dad someone reported you to adult protective services for talking dirty.Warm him.After he hears that he will watch his steps.

If this man doesn't have dementia, then he's being a disgusting pig and needs to pull his head in. Threaten him with whatever it takes to get him to behave himself. People are trying to help him and he's responding with verbal sexual abuse. It's not on - whether he's capable of following through with it or not.

On the other hand, if he DOES have dementia, this might be a symptom. Ask his doctor about it.

He does not have dementia, but is frustrated and depressed with his loss of mobility. I have recently learned (through his caregiver) that when he was in the Merchant Marine during WWII his roommate, who was twice as big as he, would rape him. He has been having bad dreams for a long time and does not sleep well, even with prescription sleep aids. I am now thinking that he (and he is agreeable to this) needs to talk with some sort of psychologist and maybe this will be the answer to his sexual behavior. Does anyone know where I can start my search for the right professional? I really appreciate all of your feedback so far.
